Thanks for all the input, I found a fire extinguisher place about 5km from where I live and rode my bike up there, the woman at the desk said shed call me when it was done but a guy came and grabbed it and said it would be 15 minutes. He was back in ten and five pounds cost me 11, so $12.xx with tax.

There is a metro station only about a 1km from there, so I would even be willing to walk it come winter

thanks for all the help everyone

Hi, im in Montreal also and i have a terrible time trying to find a place to buy and fill a co2 tank. Can you tell me your fire extinguisher place?

Sure, I don't know if they sell tanks but they will fill them for you. Both times they actually filled them while I waited!

Its called Guard-X, I actually see some of their cars all over the city.

Also, welcome!!! And good job with the search function

Just to chip in, CO2 is not CO2 is not CO2. It comes in all sorts of purities, you have to get food grade, not fire extinguisher grade. The grade is way more important than purity.
Even if it is 99.9 or even 99.99% it's still no good if it's not food grade and 99%...forget it. That 0.1 or 0.01% could contaminated with really nasty crud. For the sake of a few bucks and your well being I'd urge you to insist on food grade and check it is. Doubtless lots of people do use el cheapo without problems, but if you dont have to then don't.

These limits are deemed safe, to put a fire out it doesn't matter
Secondly there is the containers that can cross contaminate if corroded etc.
Sure this is a way to rip you off, and 99999/100,000 it won't matter, like insurance I guess, you don't need it til you need it. Sometimes perhaps mostly, ordinary CO2 might meet this spec, sometimes not.

there is a reason why benzene is set lower for consumption than for processing.
like this for examplehttp://en.wikipedia.org/wiki/Benzene_in_soft_drinks
It all depends how you value your health and other people's. Personally I'd say if you have a choice then there's no macho points for drinking welder gas or fireman foam or whatever and if there are they don't seem worth having.

La cachette du bootlegger fills them. They dont have a pump for the CO2 so you have to leave your tank there for about half a day (they freeze the bottles, connect them to their main CO2 tank, and pull them out of the freezer. As the bottle heats up it 'sucks' CO2 from the main tank.)

All in all, thats where I go. Inexpensive, good service and a chance to talk beer with the local gurus.
